Aww thanks so much

[@SkanCityAcademy_SirJohn]

disclaimer!!! kindly note that the prefix for the force in question 2 is Kilo newtons, not newtons... thank you!!! sorry about that guys....

Please help me to solve this question 1.Two forces of magnitude 3p and 2p acting at a point have a resultant R.if the first Force is double, the magnitude of the resultant is double, find the angle between the forces. Thanks.

[@thescientist5456]

Thanks again 🎉 im in south africa ❤ i just a Feel like a genius 😅🧠 Do you have any video about the Auxiliary results vector

[@SkanCityAcademy_SirJohn]

Nice feeling for you. Kindly check the playlist on basic mechanics

[@EmmanuelOseiKwame-y3q]

For the 2nd question, your resultant force was supposed to be in kN. Great job! I love your good work

[@SkanCityAcademy_SirJohn]

Yes please I realized that, thank you for your input as well. And you are most welcome.

[@emmanuelarthur3081]

Wonderful video.However you forgot to use the kilo prefix in the second example.

[@SkanCityAcademy_SirJohn]

okay, Emmanuel... thanks so much for reminding me. thanks so much for watching

[@GladysKoshie-bx8rh]

Can you help with this question:. A 100N force which makes as angle of 45° with the horizontal x-axis is to be replaced by two forces, a horizontal force F and a second force of 75N magnitude. Find F.

[@SkanCityAcademy_SirJohn]

Watch video 06 of Basic Mech playlist and attempt the question. If you still can't solve. send your solution to me including a picture of the question to me on telegram

[@nellymwila9586]

So you do the same when you've been asked to find the magnitude and direction of the sum Vector say A+B? Then again what about A-B?

[@SkanCityAcademy_SirJohn]

I don't really understand your question but if Vector A and B are parallel, then the vector sum will be A+(-B)

[@Zwalter]

I have a question, On your last problem when finding the direction why is it: Sin theta= 800 sin(60) / 721.11 and not Sin theta= 600 sin(60) / 721.11 ??? In your video, you are finding the angle between 800N and the Fr where infact you are going to solve for the angle of Fr and 600N the minus it to 30 deg. Please clarify I'm quite confuse. I got all 2 problems but the last one was questionable

[@SkanCityAcademy_SirJohn]

The reason why it is 800sin(60)/721.11 is that, in finding alpha, considering the triangle on the right, the original 800N force is parallel to the line from FR to 600N, and so, asing the law of sines, sin of alpha/ the side opposite to alpha, and that is 800N. And you follow with the rest of the solution. So that's how come it's supposed to be 800N and not 600N. Kindly reply if you still don't get it. Thanks for watching....

[@YaaKonadu-e9r]

Please i have a question: why did you place alpha there and not at the other side? is there a specific reason why that was done

[@SkanCityAcademy_SirJohn]

Kindly state the time in the video so I can help you out

[@YaaKonadu-e9r]

@@SkanCityAcademy_SirJohn The second question< the seventeenth minute

[@SkanCityAcademy_SirJohn]

You can put it on the other side, but we are looking for the easiest way to obtain the direction, that is the angle the resultant force makes with the positive x axis

[@AkachukwuIfediora-k4w]

Pls in the first example solved y didn't we use the 65 we got for the cosine rule

[@SkanCityAcademy_SirJohn]

Kindly backtrack a bit to where we defined the cosine rule, 05:45 you realized that we defined the angle theta, and that what we used for the R force expression, so we are just translating what we've learnt from that section, to solve q1

[@jerroldbartman2056]

Good information but the accent is very difficult to understand. You should really overdub the audio with someone else.

[@SkanCityAcademy_SirJohn]

great, thanks so much for your comment, sorry about that. and good luck

[@AdamMarshallIddi]

In what case will it be +2(A)(B)CosTHETA?

[@SkanCityAcademy_SirJohn]

+2ab cos (theta) is used to find the magnitude of the resultant force of two vectors a and B acting at an angle theta, While -2ab cos (theta) is used to find the third side of a triangle, with sides a and b and an angle theta

Please why didn't use kilo

for which question please?

i recently checked and realized that i didnt write the correct prefix for the force in question 2, its supposed to be kilo newtons.... so sorry about that. thank you.
